Flamingo's zijn neergestreken in het noordoosten van Italië, en dat drijft boeren tot waanzin. De roze vogels verpesten de risotto-oogst doordat ze in de rijstvelden zoeken naar algen en insecten.

"When the iPhone X portrait mode works… it really works! I took this picture at an aquarium (yes going to aquariums to get bird photos), and this guy stood still for me to take a lot of pictures. There was a green tropical background, but I nailed this one perfect picture were he came out with this beautiful black background.

Tuz Gölü'nde yüzlerce flamingo ölü olarak bulundu: Aksaray, Ankara ve Konya sınırlarında yer alan ve son yıllarda kuraklıkla sıklıkla gündeme gelen Tuz Gölü'nde kuraklıkla birlikte ölü flamingolar da görüntülendi.

Allı turna olarak da bilinen flamingoların kuluçkaya yattığı en önemli sulak alanlar arasında yer alan Tuz Gölü'nde bugünlerde yüzlerce flamingo ölmüş olarak bulundu.

This linocut shows a flamboyance of flamingos. The collective noun for a group of flamingos is a "Flamboyance". Isn't that perfect? And, ridiculously fun to say? Try it: "A flamboyance of flamingos." Alliterative, apt, succinct, this flaboyance of three pink and fuchsia flamingos are a chorus line of long-legged aquatic birds about to break out into a can-can routine.

Flamingo Fluid Dynamics, Part 2: The Game’s a Foot

Yesterday we saw how hunting flamingos use their heads and beaks to draw out and trap various prey. Today we take another look at the same study, which shows that flamingos use their footwork, too. If you watch flamingos on a beach, in muddy waters, or in a shallow pool, you’ll see them shifting back and forth as they lift and lower their feet. In humans, we might attribute this to nervous energy, but it turns out it’s another flamingo hunting habit.

As a flamingo raises its foot, it draws its toes together; when it stomps down, its foot spreads outward. This morphing shape, researchers discovered, creates a standing vortex just ahead of its feet — right where it lowers its head to sample whatever hapless creatures it has caught in this swirling vortex. And the vortex, as shown below, is strong enough to trap even active swimmers, making the flamingo a hard hunter to escape. (Image credit: top – L. Yukai, others – V.

Flamingo Fluid Dynamics, Part 1: A Head in the Game

Flamingos are unequivocally odd-looking birds with their long skinny legs, sinuous necks, and bent L-shaped beaks. They are filter-feeders, but a new study shows that they are far from passive wanderers looking for easy prey in shallow waters. Instead, flamingos are active hunters, using fluid dynamics to draw out and trap the quick-moving invertebrates they feed on. In today’s post, I’ll focus on how flamingos use their heads and beaks; next time, we’ll take a look at what they do with their feet.

Feeding flamingos often bob their heads out of the water. This, it turns out, is not indecision, but a strategy. Lifting its flat upper forebeak from near the bottom of a pool creates suction. That suction creates a tornado-like vortex that helps draw food particles and prey from the muddy sediment.

When feeding, flamingos will also open and close their mandibles about 12 times a second in a behavior known as chattering. This movement, as seen in the video above, creates a flow that draws particles — and even active swimmers! — toward its beak at about seven centimeters a second.

Staying near the surface won’t keep prey safe from flamingos, either. In slow-flowing water, the birds will set the upper surface of their forebeak on the water, tip pointed downstream. This seems counterintuitive, until you see flow visualization around the bird’s head, as above. Von Karman vortices stream off the flamingo’s head, which creates a slow-moving recirculation zone right by the tip of the bird’s beak. Brine shrimp eggs get caught in these zones, delivering themselves right to the flamingo’s mouth.

Clearly, the flamingo is a pretty sophisticated hunter! It’s actively drawing out and trapping prey with clever fluid dynamics. Tomorrow we’ll take a look at some of its other tricks.
